Frequently Asked Questions

Q: Why is the drilled shank design important for karting?

A: In high-vibration environments like racing karts, standard bolts can loosen over time. The drilled shank allows you to insert a safety pin, which physically locks the fastener in place, ensuring your critical components stay secure throughout the race.

Q: What size safety pin should I use with this bolt?

A: This bolt is designed to be used with standard-sized cotter pins or R-clips that fit through the pre-drilled hole in the shank. Ensure the pin is fully seated to prevent accidental dislodging.

Q: Can I use this bolt for any application on my kart?

A: While it is a versatile 8mm hardware piece, it is specifically recommended for critical weight attachments or areas prone to high vibration where hardware failure could compromise safety or performance.

Q: Is the 1.25 pitch compatible with standard kart frames?

A: Yes, the 8mm x 1.25 pitch is a common metric thread size used extensively in kart chassis construction and component mounting.
